Setting During the whole of a dull, dark, and
soundless day in the autumn of the year,
when the clouds hung oppressively low
in the heavens, I had been passing alone,
on horseback, through a singularly dreary
tract of country, and at length found
myself, as the shades of the evening
drew on, within view of the melancholy
House of Usher. I know not how it was-
but, with the first glimpse of the building, a sense of insufferable gloom
pervaded my spirit.
-Edgar Allan Poe, "The Fall of the House of Usher"
Briefly describe this setting in your own words.

The “big dig” the “big dig” (the central artery/tunnel project) has been complex and challenging. located in boston, massachusetts, this tunnel is eight lanes wide and three-and-a-half miles long. what is most amazing about this tunnel is that it is constructed under a major highway and skyscrapers located in boston’s financial district. construction crews used “clamshell excavators” during this dig. these machines carved narrow trenches, and then a special substance was pumped into the trench to keep the dirt from caving in. finally, steel beams were lowered into the trench and concrete was pumped in. one problem that engineers faced while constructing the tunnel is the fact that the soil beneath boston is extremely loose and soggy. engineers solved this dilemma by freezing the soil and pumping very cold water into pipes beneath the city. to strengthen the soil even further, a special type of glue was injected into the ground to with the consolidation of the soil. 23 which phrase best defines the word excavator as used in the passage? a. a device used to measure underground temperatures b. a device used to level uneven surfaces c. a device used to move heavy objects d. a device used to dig holes
